摘要
Disclosed herein are diatomaceous earth products containing reduced soluble metal levels, processes for reducing soluble metal levels in diatomaceous earth products, and methods of using the same. In particular, diatomaceous earth products are disclosed that have been treated with at least one surface metal blocking agent, and then subjected to at least one thermal treatment process to reduce the level of soluble metals associated therewith. Such diatomaceous earth products containing reduced soluble metal levels may be useful for various applications including, but not limited to, as filter aid materials.
